Abstract: ABSTRACT OF THE DISCLOSURE     A mechanism, for intermittently feeding a tape-like article along a longitudinal path, comprises a slide having a first clamping jaw and reciprocably movable parallel to the longitudinal path, and a second clamping jaw carried by the slide and movable relatively thereto toward and away from the first jaw to clamp and release the tape-like article.  At the end of the slide's forward movement, the second jaw is moved away from the first jaw and is locked in such "releasing" position.  At the end of the slide's backward movement, the second jaw is unlocked and thereby returned to its "clamping" position.  The advance in the art resides in the provision of an intermittent feed mechanism having a simple structure and enabling accurate step wise feeding of a tape-like article., Also, the invention simplifies the adjustment of the amount of feed in a single step of the device.

Abstract: METHOD AND APPARATUS FOR CONDUCTING WIRELINE OPERATIONS                IN A BOREHOLE     Abstract of the Disclosure For conducting wireline operations in a deviated borehole, a dual or two-stage locomotive pulls a wireline cable through both the entire length of 8 drill string and the entire length of a stinger therein to dock with a tool at the bottom of the stinger. The inner or second-stage locomotive then pulls the stinger out into the borehole by pushing on the bottom end of the stinger to prevent buckling the stinger. The stinger and drill stem can be assembled to virtually any length, without requiring pre-wiring. The risk of buckling upon retracting the stinger back into the drill pipe, by pulling on the cable, is reduced by the use of the special configuration provided by the present invention.

Abstract: Abstract of the Disclosure Particulate materials are blended in a vessel provided with a plurality of vertically extending conduits therein.  The vessel comprises a downwardly converging frustoconically shaped bottom wall which defines the lower region of the vessel.  The lower ends of the conduits extend through corresponding openings in the bottom wall and are connected by suitable conduit means with a solids outlet at the open bottom of the bottom wall, an outlet conduit extending downwardly therefrom with a solids flow control valve interposed therein.  A recycle conduit extends from the interior of the outlet conduit at a position above the solids flow control valve therein upwardly to a solids hopper positioned above the vessel.  A blower is connected to the upper portion of the vessel and applies vacuum thereto and to the recycle conduit for withdrawing particulate materials or solids  through the recycle conduit into the hopper.  A hopper conduit extends from the bottom of the hopper to the interior of the upper portion of the vessel and is provided with a flow control valve interposed therein.  A sample valve mechanism is interposed in the recycle conduit for withdrawing samples of the solids from within the recycle conduit.  Recycle vents communicate between the interior of the recycle conduit and atmosphere via excess flow valves to provide means for facilitating the fluidizing of solids within the recycle conduit in response to the vacuum applied thereto by the blower.  Methods of blending solids using the described apparatus are also disclosed.

Abstract: SHIELDED COMBUSTOR      ABSTRACT OF THE INVENTION.       A radial lip of a high temperature combustor liner is mechanically locked in a radially directed capture slot in a supporting shell of a combustor. In one embodiment, the capture slot is formed at abutting edges of shell sections which are joined by a weld bead.  The weld bead is accessible for grinding off to provide access to the liner for replacement. In embodiments in which a plurality of liner sections are employed, a downstream end of a liner section overlaps and shields an upstream end of an adjacent liner section including the radial lip thereof to protect the radial lip and capture slot from temperatures in the combustion zone and to channel a sheet flow of film cooling air along an inner surface of the adjacent liner.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention provides a device which serves to bridge expansion gaps such as are used in the roadways of major structures such as bridges or viaducts. The supporting por-tion of the device comprises bearers, the upper sides of which are level with the roadway.  The bearers rest on cross-pieces that are supported, in such a manner as to be able to move, with-in recesses below the roadway.  The secondary gaps between the bearers are sealed by means of elastic rubber strips.  In order that any contraction or expansion of the structure is distributed evenly across the secondary gaps, the cross-pieces are controlled by means of connecting rods.  The ends of these connecting rods are articulated onto the opposing edges of the gap.  In contrast to conventional systems of this kind, in which the connecting rods are disposed beneath the cross-pieces, in the present system the connecting rods pass through the cross-pieces.  To this end, a bearing with plastic bearing shells is incorporated in the cross-pieces which make it possible for the corresponding connect-ing rod to move and to pivot in the cross-piece.

Abstract: Abstract of the Disclosure Process and apparatus for removing light oil from solids.  The invention is particularly applicable to the re-moval of residual light oil from solids obtained in a process where aqueous solids are mixed with a light fluidizing oil and subjected to dehydration by heat evaporation.  Aqueous solids are mixed with a low viscosity, relatively volatile, water-immiscible light fluidizing oil to obtain a mixture which will remain fluid and pumpable after removal of essen-tially its entire water content.  The mixture of solids, water and fluidizing oil is subjected to a dehydration step by heat evaporation whereby substantially all of the water and at least part of the light oil are evaporated and subsequently recovered.          The light fluidizing oil is then largely separated from the solids.  The solids carrying residual light fluidizing oil are then brought into direct contact with a hot, inert gas, re-ferred to herein as "blowing gas."  The hot, inert blowing gas effects the removal of the residual light oil from the solids.          Light oil vapor removed from these solids is separated from effluent blowing gas by condensation and recovered.  Effluent blowing gas, free of light oil vapor, may be recycled.

The system includes a battery energized microcomputer controlled unit in each door which is capable of activating an electromechanical deadbolt mechanism when a magnetically encoded card bearing a selected code is inserted into a slot in that particular door, and which includes a non-contact proximity mag-netic sensor for the cards.  The microcomputer controlled unit has five levels of response, namely, guests, maid, master, grand master and emergency.  The microcomputer is programmed to respond to cards bearing a new code when a new guest inserts his card into the slot in the door, and of adjusting the unit to respond to the new code and to reject the previous card.  The microcomputer is capable not only of reading a magnetically encoded card inserted into the corresponding slot and of re-leasing the deadbolt mechanism of the door when the card bears the proper code, but it is also capable of re-cording the time and identity of all hotel personnel gaining access to the room, and of responding to a particular guest card only for a particular time period, corresponding to the duration of  the guest's intended occupancy of the room.
